Then the guy must have mis-diagnosed things.

Sorry I can't give better help...but is this switching on and off, the
same problem you had prior to changing to capacitor and contactor?

I didn't have the problem before. He said the capacitor and the contactor were about to go out and recommended replacing them.

Disregard...I let it run a bit longer and it started to run normal again. Seems fine now.

Glad it's working but I am sure the guy was a rip off.

A capacitor can be checked for value and unless the terminals are burned
there is no way one can tell if it's about to go.

As to the contactor, if the contacts were badly burned it probably was
not a bad idea to replace but normally it would not be replaced unless
the coil opened.
